Embodiment Construction

[0012] According to Figure 1, the principle is explained as follows:

[0013] Fig. 1 is a schematic longitudinal sectional view of a drive unit according to the present invention. We can see the motor EM, the isolating coating IC, the two damping plugs DP, and the two damping clutches DC.

[0014] Here the motor EM represents the appropriate electric motor, and also the gear or gear set, the brake and, if necessary, the bearing.

[0015] The motors used for this application are mainly AC induction motors with mounted gearboxes for short duration operation. It is cheaper to have gears on both sides of the motor. However, it is also known that only one gear is connected to the hollow shaft via the motor. With such a gear or set of gears, an electromechanical brake would be necessary. At least one gear at each end is required. Normally, ball bearings are used. See Figure 2 for more details.

[0016] Returning to the diagram three separate devices can be seen for acoustical...

Abstract

The invention relates to a drive unit for a Venetian blind or the like for inserting into a head rail, including an electric motor and output shafts at both ends driven via gear, where the electric motor is combined with components serving for acoustically damping and uncoupling, that are shaped such that they are insertable into the head rail together with the electric motor as well as to a Venetian blind or the like as such.

Description

technical field [0001] The invention relates to a drive unit for a shutter or the like according to the preamble of claim 1 and to a shutter or the like according to the preamble of claim 5 . Background technique [0002] Electrically driven blinds, roller blinds, projection screens, and other objects that can wrap around and off the tubes are commonly used in rooms where people stay. Usually they operate automatically, at least their accidental operation is considered to be a disturbance in the noise result. [0003] It will be mentioned that not in every application such objects are wound on and off the tube but only the driving part thereof. This does not change the stated problem. [0004] It is known to acoustically isolate the drive by surrounding the head rail with suitable material. This requires additional installation work. [0005] The technical problem is thus to reduce the installation effort. Contents of the invention [0006] According to the invention,...
